## Quick answer

The ball python is a small, non-venomous constrictor from the grasslands and forests of West and Central Africa, named for its habit of curling into a tight ball when stressed. Docile and slow-moving, it is one of the most popular pet snakes in the world and comes in hundreds of color and pattern 'morphs'. Ball pythons are long-lived, often reaching 20 to 30 years in captivity.

## Why the name?

When frightened, a ball python tucks its head into the center of its coils and rolls into a tight ball, protecting its most vulnerable part. This shy, defensive behavior, rather than biting, gives the snake its name and is a big reason it is considered easy and safe to keep.

## Help protect the Ball Python

The ball python is listed as Near Threatened, with habitat loss the leading threat to its future.
